Embed Structured Query Language in Java (SQLJ) statements in your applications
to maximize the efficiency of transactions with your databases. Before your
applications can take advantage of SQLJ, you must deploy the application and
customize the SQLJ profiles that are created. The application server provides
functionality to use SQLJ as the persistence mechanism for enterprise beans
that use container-managed persistence. Deploy the CMP beans in the application
server to enable SQLJ support.
Before you begin
You need an application that uses SQLJ and container-managed persistence.
Develop this application in Rational® Application Developer or another development
tool.
About this task
Deploy SQLJ applications in the application server to simplify the
process of SQLJ translation and bean deployment. The application server includes
these new features for SQLJ support:
- Deploying CMP beans during the application installation in the application
server.
- Customizing and binding SQLJ profiles with the administrative console
or scripting.
- Customizing and binding SQLJ applications again without needing to reinstall
the application.
You can also deploy the SQLJ application using the ejbdeploytool.
Read the topic on deploying SQLJ applications that use container-managed persistence
(CMP) with the ejbdeploy tool for more information.
Procedure
- Create a top-down mapping to a DB2® database.
- From your DB2 installation, copy the sqlj.zip file
to a directory on your workstation.
- Deploy the EAR file in the administrative console.
- Click .
- Select Local file system or Remote
file system, and browse to the EAR file.
- Select Detailed - Show all installation options and
parameters. Click Next.
- In Step 1: Select installation options,
select Deploy enterprise beans. Configure any other
options, and click Next.
- In Step 3: Provide options to perform the EJB deploy,
select SQLJ for Deploy EJB option - Database
access type.
- Enter the location of the sqlj.zip file
in the SQLj class path field.
- Complete the installation process for the application.
What to do next
After the enterprise application is deployed, customize the SQLJ
profiles using the administrative console, scripting, or the db2sqljcustomize
tool:
- For administrative console support, read the topic on customizing and
binding profiles for Structured Query Language in Java (SQLJ) applications.
- For scripting support, read the topic on the application management command
group for the AdminTask object.
- For use of the db2sqljcustomize tool, read the topic on customizing and
binding SQLJ profiles with the db2sqljcustomize tool.
